The Billboard 200:

It was a quiet week at the top of the Billboard 200. So quiet, that Zac Brown Band returned to No. 1 with its Uncaged set, selling a rather tiny 48,000 copies according to Nielsen SoundScan. There were, however, two debuts in the top 10 from the Gaslight Anthem and Passion Pit. And? Both of them scored career-high sales weeks and new peaks on the chart.

But now, let's take a look at some of the other movers and shakers on the Billboard 200 -- outside of the top 10:

-- Olympics' Isles of Wonder Soundtrack: The Olympics make its mark on the charts this week, even though the games only got underway in full on Friday, July 27. The soundtrack to the opening ceremony, titled Isles of Wonder, debuts at No. 136 on the Billboard 200 with 3,000 digital-only copies. The physical version of the 36-track set won't street until Aug. 28, more than two weeks after the games end Aug. 12.

On Classical Digital Songs, a number of Olympics-related tracks make waves. At No. 4, John Williams' "Bugler's Dream and Olympic Fanfare Melody" (from the 1984 Olympics) rises 15 slots with a 288% gain in downloads, while two different versions of "Chariots of Fire" (which was featured in the opening ceremony) appear at Nos. 5 and 6. The Williams theme is repeatedly heard throughout NBC's U.S. broadcast of Olympic events, while "Chariots of Fire" was used in a humorous portion of the opening ceremonies, involving the actor Rowan Atkinson.

-- Jennifer Lopez:
The diva debuts her first greatest hits package, Dance Again. . .The Hits, at No. 20 on the Billboard 200 with 14,000 sold according to Nielsen SoundScan. However, it's the performer's lowest-charting regular release. All of her previous albums -- except for a EP/DVD package titled The Reel Me (No. 69) -- have reached the top 12.

Dance Again fares better on the Top R&B/Hip-Hop Albums chart, where it is the top debut, coming in at No. 6. It gives Lopez her seventh straight top 10 on Top R&B/Hip-Hop Albums. She previously hit No. 1 with 2001's J.Lo and the 2002 remix set J to tha L-O!

Though Lopez has focused more on dance/pop and Latin music in recent years, nine of Dance Again's 13 tracks were hits on the Hot R&B/Hip-Hop Songs chart, including "If You Had My Love" (No. 6), "I'm Real" and "Ain't It Funny" (both No. 2, and both featuring Ja Rule).

-- ZZ Top: More Amazon MP3-fueled madness ensues on the chart, as the retailer priced a bunch of classic rock albums for $2.99 last week. One of those, ZZ Top's The Very Best Of ZZ Top: Rancho Texicano, reenters the chart at No. 30 (up 855% in sales). That returns the rockin' trio to the top 40 for the first time since 1996.

-- Emili Sande:
Though NBC didn't air her performance of "Abide By Me" during the Olympics' opening ceremonies (July 27), she still posts a big increase with her album Our Version of Events. The set returns to the tally at No. 126 with a 72% gain.

-- Toby Keith:
Fueled by the success of the single "Red Solo Cup," his Clancy's Tavern album (No. 130) has spent more weeks on the tally (40) than any of his last four studio albums.

-- Donna Summer:
Her budget-priced hits compilation The Best of Donna Summer: 20th Century Masters - The Millennium Collection (No. 155 this week) has earned more weeks on the list (seven) than the late diva's final studio effort, Crayons. The latter spent six weeks on the tally in 2008 and 2009.
